Actions with operating disturbances
In the event of malfunction or operating disturbances first
Low room temperature
Cause: Compressor and electric element do not
heat up.
Action: Check and replace the any blown circuit and
main fuses.
Cause: The compressor does not start because of a
too low value set on the heating curve.
Action: Check and possibly increase the Heating
curve offset (knob on the front panel) or
Curve slope (see section Room tempera-
ture.
Cause: The compressor is not running due to tripped
internal overheating protection.
Action: Automatic resetting after cooling for a few
hours.
Cause: Possible earth circuit-breaker tripped.
Action: Reset the earth circuit-breaker, if the earth
circuit-breaker trips repeatedly, call an electri-
cian.
High room temperature
Cause: Incorrect setting of Curve slope and/or Off-
set heating curve.
Action: Adjust the setting. Also see section Room
temperature.
Low hot water temperature or
no hot water
Cause: Large amount of hot water drawn off.
Action: Wait until the water heater reheats.
Cause: Compressor and/or immersion heater does
not heat up.
Action: Check and replace the any blown circuit and
main fuses.
Cause: Too low start temperature on the CPU-unit
(34).
Action: Adjust the hot water setting, see the section
Description of functions - Basic functions >
Hot water production.
Cause: Possible earth circuit-breaker tripped.
Action: Reset the earth-fault breaker. If the earth-
fault breaker trips repeatedly - call an electri-
cian.
check the points below:
As FIGHTER 1330 can be connected
to a large number of external units
When the switch (8) is turned to the "
outputs for the external heating medium pumps (VBP3
and VBP4), internal heating medium pump (VBP-A)
and the additional heat outputs (ETS-3/OP) and, when
Expansion card 1 is connected, additional heat output
ETS-6 are activated.
All control from the heat pump ceases, which means
that when the oil boiler is connected, the shunt (SV-P)
must be controlled manually.
When connecting an external electrical additional
heater, a thermostat must be connected to the control
circuit. This thermostat must be set to approximately
10 °C above the maximal flow temperature (menu 2.4)
to not have an effect in normal operation. However, in
standby mode the thermostat's cut-out value can be
lowered if necessary.
Note that hot water is not produced in standby mode.
